Presentation on theme: 'From Swarm Intelligence to Swarm Robotics'— Presentation transcript:From Swarm Intelligence to Swarm RoboticsGoal Help start a discussion to clarify some concepts related to swarm robotics Clarification is useful because there is some confusion in what it means doing research related to swarms It appears that the term ‘swarm’ is used somewhat indiscriminatelyEvolution of swarm terminologySwarming Swarm intelligence Swarm optimization Swarm robotics A starting point for discussionWhy ‘swarm’? Not just a buzz word for a cooperating groupDistinct features: ‘Intermediate’ number of units:.
Swarm robotics ppt. 1. MAHAVEERINSTITUTEOFSCIENCE&TECHNOLOGY DEVELOPMENT OF AN AUTONOMOUS MICRO ROBOT FOR SWARM ROBOTICS Presented by K.Harshit reddy M.Raju M.Maheswara reddy M.Rajender MD.Ankoos M.Shwetha. Objective The objective of our project is to build a small robot whose behavior can be traced from swarm intelligence. The robot is either controlled by a master control robot or can be able to take its own simple self-decisions automatically. This robot is also interfaced with a zigbee module that connects it to its master control unit, and can perform actions according to the command issued by master control unit.
CONTENTS Introduction Swarm Robotics Block Diagram Hardware Components Categories In Swarm Advantages Applications Output. INTRODUCTION The project is designed to build a small robot whose behavior can be traced from swarm intelligence. Swarm Robotics is an approach to the coordination of multi robot systems which consist of group of micro robots. These micro robots communicate with each other to perform a specific task. The robot is either controlled by a master control robot or can be able to take its own simple self-decisions automatically. LPC 2148 IR SENSORS ZIGBEE LCD L293D (DRIVER IC) MOTOR 2 MOTOR 1 Swarm Robotics Block Diagram. Block diagram description A microcontroller which is interfaced with an array of IR sensors, these IR sensors are fixed on the robot in such a way that they can sense any object present near its surroundings.
The output of IR sensors is fed to the microcontroller that is programmed to take self decisions over changing the direction of the robot movement. The position control of the robot is achieved by DC motors and their drivers. This robot is also interfaced with a zigbee module that connects it to its master control unit, and can perform actions according to. Behavior of Swarm robotics.
HARDWARE COMPONENTS LPC2148 Micro Controller Zigbee IR Sensors L293D IC Motors LCD. Power Supply Transformer Transformers convert AC electricity from one voltage to another with little loss of power. Transformers work only with AC and this is one of the reasons why mains electricity is AC. Bridge rectifier A bridge rectifier can be made using four individual diodes, but it is also available in special packages containing the four diodes required. It is called a full-wave rectifier because it uses the entire AC wave (both positive and negative sections). Capacitor A capacitor is a two terminal passive electronic component consisting of a pair of conductors separated by a dielectric.
The capacitor blocks DC current and allows AC current. Regulator Voltage regulator ICs are available with fixed (typically 5, 12 and 15V) or variable output voltages. LPC2148 Micro Controller Pin Diagram.
Features of LPC2148 It has 2 ports,each port consist of 32 pins total 64 pins. LPC2148 is the widely used IC from ARM-7 family. The ARM7 is a general purpose 32-bit microcontroller, which offers high performance and very low power consumption. It is manufactured by Philips. LPC2148 is a LQFP64 package.It is a RISC processor.
Ram 32kb,Rom 512kb. Zigbee Technology ZigBee is a wireless technology. IR Sensors Need Of IR Sensor Because it has a good range which fulfills our requirements. Working Of IR Sensor The working principle is totally based on change in resistance of IR receiver, which is similar to reflection of light.
Introduction To Robotics Ppt
Here in this sensor we connect IR receiver in reverse bias so it gives a very high resistance if it is not exposed to IR light. L293D IC It is a 16 pin configuration. Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal.
Motors An Electric DC motor is a machine which converts electric energy into mechanical energy. The working of DC motor is based on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a mechanical force. Liquid Crystal Display (LCD) LCD is a type of display used in digital watches and many portable computers. Here we use a 14 pin single row LCD of the size 16X2 (16X2 means 16 characters in the Colum and 2 rows for display). Communication In Swarm Robots For working in a swarm, the master and slave has to communicate with each other. For this we use transmitter and receiver. The type of transmitter and receiver depends upon the range of communication.
In the communication process, microcontroller plays a key role. Categories In Swarm Master Robot This controls all the other robots in swarm. There will be only one master. They are intended to guide the slaves. They take decision from their own under critical conditions. Slave Robot This will be controlled by the master robots.

There are so many slaves present in a swarm application. They are intended to do certain task given by the master. They can’t take own decisions by their own. ADVANTAGES Man power not required.
Easy to use. Can be used to do the tasks which are hazardous for humans Time consumption is less. APPLICATIONS Robot applications. Military applications. Security applications.
